I have been noticing from time to time my A/c doesn't blow at as it should during certain times. It does fine early first crank in the morning but if I do alot of running around all day I notice the air flow seems to get restricted. I took the blower out and works fine at all speeds the filter is fine also. Is it possible that it could be icing over and melting over night......because I've started noticing the the front passenger floor is always soaked with water. Note: I recently had tubing work done and a/c recharged. Does anyone who the layout of the duct system (2007 4Runner Sport)?
